Line m passes through point (5, -8) and has a slope -3. what is the equation for the line in point-slope form?
- y - 8 = 3x - 15
- y + 8 = -3x + 15
- y = -3x + 7
- y - 8 = 3(x - 5)

SECOND OPTION.

Step-by-step explanation:

The Point-Slope form of the equation of the line is:

Where is the slope of the line and is a point on the line.

In this case we know that the slope of the given line "m" is:

Then, since it passes through the point (5,-8), we can identify that:

Therefore, knowing these values, the next step is to substitute them into the equation in order to get the equation for the line "m" in Point-Slope form.

Then, this is:

We can simplify it:

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
